3D Content Delivery to Fixed and Mobile Users

The delivery of 3D video services to individual users poses more challenges than conventional 2D video services due to the large amount of data involved, diverse network characteristics and user terminal requirements, as well as the user’s context (e.g., preferences, location).

Scalable and Resource Efficient 3D Video over Broadband Wireless Access Networks

• The effective exploitation of importance and redundancies in 3D video data representation formats and coding approaches for improving the system performance in terms of the efficient utilisation of the available resources;
• Scalability concepts for handling 3D video communications with heterogeneous terminals in the network;
• Error Robustness and Resilience for 3D Video Transmission.

Multimedia Broadcasting using Cellular Broadcast Techniques

• Take advantage of already deployed network infrastructure for the delivery of multimedia content to large-scale user communities;
• Provides an efficient transmission method in the downlink direction for the concurrent transport of data common to a group of end-users through a shared radio resource;
• Enables bandwidth intensive applications (e.g., mobile TV, mobile 3DTV).

Quality-Driven Cross-Layer Design

Investigating the interaction and cooperation between video coding and the transmission characteristics of wireline and wireless networks including utilised transmission protocols and error protection mechanisms.

Development of Transmission System Test-beds with IP-based Multimedia Applications

• Offline transmission system simulators are not very well suited for investigating real-time multimedia applications behaviour (e.g., end-to-end QoS, end-user perception);
• Allows for real-time configuration/tuning of system parameter settings at different layers.
